Be it known that I, JOHN V. BOLANn, a

-citizen vof the United States, residing at St.

4S'Jpecifl.cationof Letters Patent. Applidaon filed January 26,1906.' seal No. 298.025.

Louis, MissourL-have invented a new. and

useful Chimney, of which 'the followingis a specification.v y

' This invention relates tochinmeys, and consists in the general construction and far- .rangement of the chimney, which comprises a base portion reinforced by anchored metal beams to which are connectedtheinclined lower endsof vertical metallic reinforcements n embedded in concrete, the lower portion of the'chimney comprising, referably, two con"- centric walls, between w 'ch is an air-space having access to theexteriornear'the top' and at the bottom thereof.' This arrange'- ment of the 'air-space and the. draft and discharge outlets tively, near its upper and lower ends, facilit erefrom, arranged tatesthe circulation of theiaireciirrents and therethrough. p. Y

' With hese varionsffeatures'ofi'construction in 'view my invention consists' lalso of respecadditional improvements, which, to etherv with'their advantages, are herein fuly described.

In `the accompanying drawings', which `form part of this specification, higu'r'e 1 is a.

vertical sectionalr view of a ,chimney constructed in accordance with my invention.

`Fi .p 2 is la view, partially` brokenr andpar- 4tia ly in section, of one portion of the chimney. ylii 3 is a sectional view on the line 3 3 a part ofthe concrete-work of the chimney I type within ,an .excavation for the base areA p laid two metal beams 1, land with their endsy excavation, so that when the' concrete 1 saidI beams are4 entirely` ,embedded`V They vare5preferably'l` of though-Mitre isflaatab' 0fssid @iterations wading-Quia chimney.

ward from the'fco'rners. Over' each corner of they base-frame' so formed said beams 1 and 2- is'passed anV anchor 4, These .anchors may be of lany preferred design land I have illustrated only one form, which consists of a substantially Ufshape'd strap, between the legs of which are, the corners ofthe baseframe-that isjto saygtheends of thebeams 1 land 2.v The extrmi'tiesof the legs of these anchors are `angular, as indicated yat 5.. 'The excavations are iilled with concrete after the anchors are positioned7 as also is -the base excavation after the metal. reinforcements are positioned. L

. An ann'lar series 'of channel-beams 6, pref-` erably wir h their vchannels inward, is' provided ,for the outerwall`7 ofthe lower part of the chimney, the lower extremities extending obliquely outward andjhaving hooks extendf lng around under theiianges of the I-beams 1 and2,1as shown at .8, thereby firmly connecting them to the base-frame, which latter channel-beams 9 lare provided yandl anchored 'for the reinforcement 1n the innerwall 10, all ofthe channel-beams of each series being The superstructure having these reinforcing-beams embedded therein and the lower ends of the beams fastened to the base-frame to prevent slipping ofthe said reinforcing-beamsis a,

,The air-'space 12 separates the outer wall 7l -is strengthened by the anchors 4. Similarly,`
